One Direction were apparently scared they'd look tame if they appeared on a chat show with Grace Jones.

The British boyband are in the last stages of a whirlwind promotional push, before they go on hiatus in the new year (16). They've played the last few dates of their On The Road Again Tour, appeared on the UK X Factor and conducted countless interviews before they say goodbye to their fans, including a forthcoming appearance on the Jonathan Ross Show this Saturday (21Nov15). Grace was slated to appear with them, but the group appear to have had other ideas.

"Grace is so entertaining and unpredictable that 1D feared they would look tame in comparison," a TV insider told Britain's The Sun newspaper. "Instigating the termination of a booking shows just how arrogant the band have become.

"She was not happy with her treatment and felt it showed a complete lack of respect from young guys."

Instead of Grace, British comic Michael McIntyre will join One Direction. An insider close to the band says the decision came about purely for practical reasons, and was a choice made by management not bandmembers Harry Styles, Louis Tomlinson, Liam Payne and Niall Horan.

"Jonathan's show was going to be a 1D special, with room for one guest, and management felt it was appropriate someone they were friends with should appear alongside them," the second source said.

Grace fans need not despair though, as rival talk show host Alan Carr will feature the 67-year-old on his Friday (20Nov15) show.

One Direction pre-recorded their Jonathan Ross slot and have now flown out to the US to carry on the promo trail. The Sun reports that two planes carried the boys across the Atlantic, with Harry and Niall taking an early flight and Liam and Louis arriving later, indicating tensions could be high between the band.
